Designing Peculiarities and Classification of Compositional Technologies in Mechanical Engineering

Abstract

Scientific technical progress demands of technologists decision of questions concerning cardinal improvement of quality of engineering products, and also providing of breakthrough aggregation of features and their practicality measure. In particular, it is necessary for hardware which works under severe operation conditions, and to features of which great demands are made. There are a lot of different functions which affect products in operation conditions. And these functions have variable action parameters. That fact in some cases leads to quick product function loss and to reduction of operating properties of machine or technological system. So, engineering products should be provided by unconventional properties [1, 2, . In order to resolve the problems we need nontraditional approaches in development of fundamentally new technologies. They should allow solving complicated problems of new generation of machines development with properties composition, got through application of different in significance technologies [.

Determination of Stressed-Deformed State of Fine Disc Tools with Inner Cutting Section under Conditions of their Pre-Stressing

“…Fig. 1, presents a cutting tool of a ring type with internal cutting piece, designed on the basis of controlled impact, ensuring cut's width less than 1mm, which is mounted inside a rigid yoke, by means of stretching segments, fixed on the external part of the ring, a possibility of their radial motion being specified [3]. For evaluation of stress-deformed state of this disc tools of modified design with internal cutting part the disc.…”

“…So, this work is aimed at solving of the problem of designing fine disc tools with internal prestressed cutting part of the disc of the tool and ensuring a possibility of controlling their properties [3].…”

Bipolar resistive switching with unidirectional selector function in nitride/oxide heterostructures

“…Recently, NAND flash, which mainly occupies the nonvolatile memory market, has been stacked vertically to increase memory density. Although it is difficult to compete with the vertical type NAND flash in the cost-effective high-density memory market, the resistive switching memory development is under way for storage class memory (SCM), embedded memory, and synaptic devices for hardware-based neuromorphic [1][2][3][4][5]. Resistive switching memory has the advantages of easy CMOS integration, fast switching speed, and low-power operation [6][7][8].…”

Special physical readiness estimation during pre-competitive period in sports aerobics

“…2019;14(1): 23-28. DOI 10.14526/2070DOI 10.14526/ -4798-2019 Nowadays great attention is paid to university sport development [1,5,15,16]. The period of studying at a higher educational establishment is presented as a favorable period for going in for different kinds of sports.…”

“…They demonstrate difficult acrobatic elements to highly intensive music during the performances [3,4,9,10]. Competitive programs fulfillment demands a complex of physical qualities: power, quickness, endurance and flexibility.…”
